Answer:
-34/3
Step-by-step explanation:
2/3(1/4x-2)=1/5(4/3x-1)
2/12x-4/3=4/15x-1/5
1/6x-4/3=4/15x-1/5
1/6x-4/15x=-1/5+4/3
-1/10x=-3/15+20/15
-1/10x=17/15
x=(17/15)/(-1/10)
x=(17/15)(-10/1)
x=-170/15
x=-34/3
Answer:
The answer to the promblem is -7
Let s represent the measure of the second angle.
The measure of the first angle is 15° less than the second, so we can represent the first angle by (s-15).
The measure of the third angle is 45° more than half the second, so we can represent the third angle by (45+(s/2)).
The sum of these angles is 180°, so we can represent the sum as
... (s-15) + s + (45+s/2) = 180
Collecting terms, we have
... 2.5s +30 = 180
... 2.5s = 150 . . . . . . subtract 30
... s = 150/2.5 = 60 . . . . divide by the coefficient of s
The first angle is 60-15 = 45.
The second angle is 60.
The third angle is 45+60/2 = 75.

The sum of the three angles is 45 +60 +75 = 180.
